Excerpt from "Ask Ausiello: Spoilers on 'House,' 'Bones,' 'Grey's,' 'Burn Notice,' and more!"
Question: What’s going on with Katherine Heigl? Is she ever going to be returning to Grey’s Anatomy? —Hannah
Ausiello: Last I heard, she’s due back on the Grey’s set at the end of the month, which means we probably won’t see Izzie again until late April. Coincidentally, that’s right around the time a very special patient will be checking into Seattle Grace: Alex’s brother! Sources confirm to me exclusively that Grey’s is currently casting the role of Karev’s estranged sibling. For those keeping score at home, this will be our first time meeting a member of Karev’s troubled clan. Look for bro to dredge up a lot of ugly family history, including that nasty business about daddy beating mommy.
Question: What’s up with the Mercy West residents on Grey’s Anatomy? Will they be sticking around next season? —PT
Ausiello: I’m fairly certain one of them won’t be. A reliable source tells me that one of the four has received his/her walking papers and will exit the show before the end of the season.
